This yeast produces a very malty, Bock-like style. It does not finish as dry as WLP830 German Lager. Give it a try in Oktoberfests and Bocks. Dr. White of White Labs also suggests this strain for Canadian lagers.

We Recommend you make a yeast starter for all lagers. Because of the cold environment you will need about 4 times as much yeast to successfully ferment a lager. If you don't have a yeast starter pitch 2-4 vials at 60-70F and cool to 48-52F within 12-18 hours. To ferment lagers like the German's and Czech's make an active starter of 2000ml per 5 gallons. Pitch at 45-48F and let it naturally rise to 48-52F. Hold your fermentation at 48-52F for 4-6 weeks in the primary. A diacetyl rest is recommended after the last week of fermentation. Raise to 55-58F for 3-5days and crash to 40F. It is normal if lager fermentation takes 3-4 days to show any sign of krausen after pitching yeast.

Attenuation: 65-73%
Flocculation: Medium
Fermentation Temp: 52-58F
Wyeast Equivalent: 2206 Bavarian Lager

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

I was actually going to get your WLP830 but I'm actually making a Marzen so this seems more appropriate.

Great Lager Yeast
Have used this strain of yeast for years in German style Lagers, of which I am particularly fond of, given my German heritage.

I make a healthy starter prior to pitching to avoid slow starts as Joseph P. commented.

Slow but tasty
This yeast took a very very long time to get going, even with a starter. A week after pitching and I was getting nervous, but finally it went. After a long lager it has made a smooth and tasty marzen; it just needs patience at the start.
